If you have walked, run, or paddled the south shore of Lady Bird Lake at dusk in late September for the past two falls, you already know what the historic Seaholm Intake Facility looks like when it stops being a quiet concrete shell and starts being a screen. The Art Deco pump house sat mostly forgotten for close to three decades after it was decommissioned in 1989. Then, in 2024, someone had an idea about what to do with that blank facade, and the building has been putting on a show for two nights every fall ever since.
This year the show is back, on Friday, September 25, and Saturday, September 26, at dusk. But if you are planning to catch it the way you caught it last year, from the same spot on the Butler Trail with the same expectations, it is worth knowing that the event underneath the lights has changed more than the artwork on the wall.
Where the idea came from, and where it's gone
The origin story is small and specific enough to be worth repeating. Design Austin co-curator Emily Eisenhart was on a spring architectural boat tour of the lake, looking at the intake building's cast concrete facade, when the idea hit her that the building couldn't be painted, since it's a protected historic structure, but it could be temporarily lit. She has called that first idea "a total creative experiment." That experiment, WaterWork, debuted in 2024 as a two-night projection-mapped installation put on by The Trail Conservancy and Design Austin, showing roughly a dozen artists' work on the building's face.
It came back in 2025 with the same footprint: two nights, fifteen local artists, the same two presenting organizations. This year the numbers moved. Twenty-two Central Texas artists, including names like Beili Liu, Bethany Johnson, and Hillerbrand+Magsamen, have work in the 2026 lineup, up from fifteen the year before. And the presenting list grew too. The City of Austin's Arts, Culture, Music and Entertainment department has joined The Trail Conservancy and Design Austin as a co-presenter for the first time.
That combination, more artists and a city department now attached to the program, is the part worth sitting with if you live near the trail. A one-off creative experiment and an annual civic-backed program don't draw the same crowd, and they don't behave the same way on the ground. What started as an idea from a boat tour is now something the city has put its name on.
The building the lights are hitting
Part of why this keeps working as an idea is the building itself. The Seaholm Intake Facility was built in two phases, in 1950 and 1955, as the pump house for the Seaholm Power Plant, and its cast concrete silhouette is a genuine example of midcentury municipal Art Deco design. It powered the city until 1989, then sat unused and largely inaccessible for decades. The City of Austin finished a first phase of redevelopment work on the site in 2022, and The Trail Conservancy is currently running a $15 million capital campaign to fund a second phase that would open the building's interior to the public on a regular basis. Until that happens, WaterWork is one of the only times all year the building becomes something other than scenery you pass on a run.
Two dusk rituals, the same two nights
Here is the detail that actually changes how you should plan around this. Late September on the Butler Trail already has a dusk ritual built in: the bat colony under the Congress Avenue Bridge, which flies out at sunset from spring through October. Regulars who already time an evening walk or a bike ride around watching the bats emerge are going to find the trail doing double duty on September 25 and 26. Two dusk spectacles, both drawing people to the water's edge, on the same two nights, a few miles apart on the same trail.
That overlap is not a reason to skip either one. It is a reason to think about which stretch of the Butler Trail you are actually standing on. The bat crowd gathers around the Congress Avenue Bridge. The WaterWork crowd gathers around Auditorium Shores and the Pfluger Pedestrian Bridge, on the opposite side of the lake from the bridge. If your usual evening loop passes both, you are choosing between two different kinds of company depending on which direction you turn.
How to actually see it if you already live here
For anyone treating this as a normal night on a trail they already know rather than a special outing, a few practical notes make the difference between a good view and a crowded one:
- Shoreline viewing is free, and the two best-documented vantage points are Auditorium Shores and the Pfluger Pedestrian Bridge, both regular stops on the Butler Trail loop.
- If you are walking in from the shore, arrive before dusk. Prior years have filled up the good sightlines quickly once the light starts to go.
- Personal watercraft is a real option here, not a novelty one. Kayaks and paddleboards are common on the water for this event, but lifejackets and lights are required after dark.
- Design Austin runs a small number of ticketed boat cruise seats for a closer view with narration from curators and artists. These have sold out quickly in past years, so this is not a plan-it-that-afternoon option.
- If you already have a Wednesday habit of catching Music on the Trail at the Rainey Street Trailhead lawn, note that WaterWork runs on its own separate schedule and does not fold into that weekly series.
Why this is worth knowing before the two nights arrive
None of this changes what most people already do on the Butler Trail most evenings. It is still a ten-mile loop that the city itself counts at more than 2.6 million visits a year, and September 25 and 26 will not be the only good nights to be out on it this fall. What is worth carrying into those two specific evenings is that the event has grown since you last saw it. More artists, a new city partner, and a building that is slowly being pulled back into public use one capital campaign at a time. The version you remember from 2024 or 2025 was smaller, quieter, and less official than the one arriving this year.
If you already live along this stretch of the lake, that growth is the useful piece of information. The trail you know is about to get busier for two nights, not because the route changed, but because the thing happening on it did.
If you're weighing what it actually means to own property along a stretch of Austin that draws this kind of civic attention and investment year over year, that's a conversation worth having with someone who tracks this market closely. Michael Langford works across Austin and the Hill Country and is glad to talk through what a specific block, or a specific view of the lake, is actually worth right now. Let's Connect.
